+ 1. Fig. 1 depicts the model of a coaster wheel.+ (1) If the velocity of point A is Va, the angular velocity wi = +10 deg/s() ist constant, and there is no wheel slip, determine the velocity of point B and C+ and the angular velocity W2.+ (2) Continuing from (1), determine the acceleration of point B and Cot (3) Suppose that the velocity and acceleration of point A are Vaand aa, the change rate of the angular velocity wiis aa= +2deg/s (), and there is not wheel slip, determine the velocity and acceleration of point C. (4) Continuing from (3), determine the angular acceleration of the disk. + Fig. 1+ 2. (20%) As we learned in the class that the U.S. Golf Association limits the COR oft golf balls at 0.83.+ (1) What is the impact to the golf player if the COR of a golf ball is much lower+ than 0.83? (2) Design an experiment to determine the COR of a golf ball accurately. Describe! your method as detailed as possible.
